Focus of research

 

Orthopedic Imaging
In a longstanding cooperation with the depts. of Radiology, Plastic & Reconstructive Surgery and Orthopedics of the AMC we develop and evaluate 4D-imaging equipment for analysis of 3D patterns of movement of the wrist. This technology enables acquisition of novel 4D diagnostic information which facilitates treatment decision making in wrist problems. Current clinical research using 4D imaging is focused on measurement of dynamic joint space thickness as well as the effect of surgical interventions on 3D motion patterns of the wrist joint.
In a second orthopedic application we develop image based surgical planning and per-operative image analysis methods for minimally invasive corrective osteotomy procedures. This application has been developed in cooperation with our European consortium partners in the MEDIATE project. Currently, a multitude of applications emerges based on technology developed in MEDIATE, including planning of knee surgery and designing patient specific implants.
In cooperation with the Internal Medicine and the Radiology departments we recently started a cooperation with the VUMC on the assessment of bone mineral density in obese patients. Dedicated imaging protocols are being developed to increase the accuracy of bone mineral density measurements and differentiation of bone minerals from bone marrow and fat. In view of the alliance between VU medical center and the AMC this research will be centered in the recently founded MOVEMED institute.
 

Cardiovascular Imaging
In close cooperation with the Radiology department and several clinical departments we develop methods for cardiovascular imaging and image analysis. Focus in this research topic is on image analysis for CT-perfusion imaging, Transcatheter Aortic Valve Implantation (STW project: CARISMA) and remote image analysis for trauma (European grant: MEDUSA) .

Curriculum Vitae

Geert Streekstra received his master degree in Technical Physics at the Twente University in Enschede in 1988. In the same year he started his Ph.D. research at the department of Medical Physics of the Utrecht University. In Utrecht he designed and implemented a rheoscope for the measurement of deformation and orientation of red blood cells in flow and developed a theoretical description of the light scattering by red blood cells in an Ektacytometer. In 1994 he received his Ph.D. degree and started as Post-doc at the University of Southern California to investigate the utilization of the light scattering theory for measurement of red cell deformability in patients with Sickle Cell Disease.
In 1995 he started as a researcher at the dept. of Experimental Cardiology of the Utrecht University where he worked on the development of an automated grafting method for bypass surgery. From 1996-2000 he was Post Doc in the depts. of Intelligent Sensory Information Systems and Molecular Cytology at the University of Amsterdam. In Amsterdam the research activities were devoted to image analysis in 3D confocal microscope images in particular detection of threadlike structures and analysis of time sequences.

Since 2000 Geert Streekstra has been assistant professor at the department of Biomedical Engineering and Physics. In the last 4 years the assistant professor position was for 50%. The other 50% was a position as a clinical physicist at the Radiology Department.
